18 days out from the 137th running of the Kentucky Derby (15 days until Post Position Draw) and nowhere can definitively say which 20 horses will break form the starting gate on May 7th at approximately 6:20pm EDT.

On Monday, Astrology was officially within from consideration as his trainer Steve Asmussen indicated that the son of A.P. Indy would run in the Jerome Handicap at Aqueduct on Saturday, April 23rd. Then there’s Jaycito who on April 9th was scratched from the Santa Anita Derby due to a bruised right front foot/hoof but put on a path to run in Saturday’s Grade 2, $200,000 Coolmore Lexington Stakes at Keeneland., is now doubtful to make that start. He has not worked since April 2 and has not raced since March 12, when he finished a distant second in the San Felipe Stakes at Santa Anita in his only start of this year.

Jaycito currently has $250,000 in graded stakes earnings, which puts him in the field for the Kentucky Derby. But if he defects, that would open another spot on the graded stakes earnings list, and there are several others currently in the Top 20 whose status is not solidified, including J P’s Gusto, The Factor, Watch Me Go, and even UncleMo.

The Derby field is limited to 20 runners. If more than 20 enter, as seems certain this year, the field is determined by earnings in graded stakes races. Below chart shows those runners, in ascending graded stakes earnings order, whose connections are considering or have confirmed their intention on entering the Kentucky Derby.
